VENTILATING SYSTEM.

Specification of Letters Patent.

Patented July 2, 1918.

Application filed July 80, 1915. Serial No. 42,875.

To all whom it may concern:

Be it known that I, DENTON K. SWART- wou'r, a citizen of the United States, residing at Cleveland Heights, in the county of Uuyahoga and State of Ohio, have invented a certain new and useful Improvement in Ventilatin Systems, of which the following is a full, 0 ear, and exact description, reference being had to the accompanying drawin s.

This invention relates to car ventilating systems, and has for its general object to provide for cars a system of ventilation which may be conveniently ap lied thereto without involving any material chan es in the construction thereof-the venti ating system constituting my invention being capable of application as an attachment to existing cars. A further general object of the invention is .to provide a ventilating system which can be applied to cars with a minimum of expense but which will, nevertheless, operate with a maximum of elliciency. Further and more limited objects of the invention are to provide for cars a ventilating system which is operated by induced draft, when the car 1s running in either direction; to distribute the entering air into the aisles without exposing the passengers to chilling drafts or otherwise ineommoding them; to provide such systems with means whereby the incoming air may be suliiciently warmed to overcome the chilling efi'ect thereof; also to discharge the air through the lavatories and closets in such manner as to prevent the dissemination of odors. \Vith the fore oing objects in view, the invention may be further and more generally defined as consisting of the combinations of parts and elements embodied in the claims annexed to and forming part hereof and illustrated in the drawings,wherein Figure 1 represents a sectional elevation of a little more than half of a car having my invention applied thereto; Fig. 2 represents a sectional plan view of such car; Fig. 3 a transverse sectional view through the ear; Fig. 4 a top plan view of the central portion of the car; and Fig. 5 a plan view of one of the dampers whereby the distribution of air from the air distributing duct may be controlled.

Describing by reference characters the various parts illustrated in the drawings, 1 denotes generally a car body, 2'the roof, 3 the floor, and t the aisle between the seats 5.

6 denotes a stateroom having a doorway 7 and a lavatory 8; and 9 denotes the usual washroom having the closet 10 and the doorway 11. The lavatory 8 is provided with a vertical discharge fine 8' having air inlet openings 8 located above the washbowl and commode. 10 denotes a similar discharge flue having inlet openings 10 similarly loeated.

As shown herein, the means for receiving, supplying, and distributing air to the interior of the car comprises a pair of oppositely extending ducts (which may be conveniently located below the central section 2 of the roof 2) said ducts communicating at their ends with the opposite ends of a distributing duct, located therebeneath, and provided with suitable damper-emitroilledl discharge openings, the whole providing a conduit whereby the ail-collected and supplied by the first two ducts may be distributed in the most oflicient manner to the interior of the ear. tioncd are shown at 11 and 11?, and each one extends from the central portion of the car to an end thereof. The duct 11 is provided at its receiving end with a laterally extending branch 12, said branch preferably resting on top of the roof 2 and having at its outer end oppositely extending inlet branches 13, the last-mentioned branches extending in the direction of the length of the car whereby air may be conducted to the receiving end of the duct 11 from one or the other of the branches 13, according to the direction in which the car is moving. In order to prevent the air which enters one of the branches 13 from passing out through the other branch without being directed into the duct 11, a damper 14. provided with an operating handle 14. is provided at the junction of the branches 13 and is adapted to be swung across either of the passageways connecting such branches with the lateral branch 12. The duct 11 is similar in all respects to the duct 11, with the exception that it extends in the opposite diroction from the central portion of the car to an end thereof. The parts 12", 13* and 14 are substantially identical with the parts 12, 13 and 14. respectively.

The ducts 11 and 11 are separated from the distributing duct 15 thereheneath by means of a partition 16. This partition terminates somewhat short of the ends of the ducts l1 and 15, whereby a passageway 17 The two ducts first men- 'return pipe is indicated at 23.

is formedaround each end of the partition,-

and the air supplied to the ducts 11, 11' is conducted around the ends of such partit on and into opposite ends of the distributing duct 15. I

It will be observed that the distnbutmg duct 15 is located immediately above the aisle 4 and that this duct is provided'with discharge outlets 17 which are so arranged as to distribute the air uniformly to the 1nterior of the car above such aisle. These openings will be of an aggregate .area sufiiclent to supply the maximum deslred quantity of air to the interior of the car. For the purpose of controllin th1s supply, I prefer to provide these out ets w th controlling dampers which ma convenlentl consist each of a disk 18 aving radia y arranged slots 18 therein adapted to register with corresponding outlet slots 18" in the bottom of the duct 15. The dampers may be conveniently supported between the bottom of the duct 15 and flanges 19 projectlng inwardly from the sides of the duct and engaging the edges of the dampers.

In order to prevent the air wh1ch 1s su plied to the car from unduly chilllng t e occupants, I provide means for heating the entering air before it may reach the dis-- tributing duct. For this purpose, I place within each of the ducts 11, 11 one or more heating coils, indicated at 20, which coils may be conveniently supplied by the steam used to heat the car and which may be conveyed in the usual heating pipes 21, 21. The p'pe connecting the supply plpe 21 and one of the coils 1s indicated at 22 while the pipe connecting the coil and the Suitable valves will be provided, preferabl at the junction of the pipes 22 and 23 wlth their respective supply and return pipes, to enable as much as may be desired of the steam entering the suppl pipe to be directed into the heater 20. T ese valves are indicated conventionally at 24.

Some of the air entering the car may be conveniently and efliciently discharged through the stateroom and the lavatories. At the bottom .of the stateroom door 7, a grating 7 is provided whereby the ventilatair may pass into said stateroom. Circu ating through the stateroom 6 and the lavatory 8 thereof, it may escape through the discharge flue 8, which discharge pipe may be provided with a cowl 8 whereby the air assm through this outlet duct may be disc arge in a direction the reverse of that in which the car is moving. The inlet into the duct 8 will preferably be located slightly above-the commode and the basin, whereby odors will be effectively conducted away through the discharge flue.

The main discharge for the car will be through the outlet shafts 25, located in the ate direction to cut off the forwardly aisle near each endof the car. Each shaft 25 will preferably be provided with a grated inlet 26 and with an outlet provided with a cowl 27. 'Each lavatory 9, in the closet thereof, is provided with a discharge flue 10" havingthe inlet openings 10 arranged above the commode, in the same manner as the inlet openings of the shaft 8. In addition, in the lavatoryor washroom proper, an additional discharge shaft 10 may be provided having inlet openings 10 arranged in the same manner as the inlet openings 10 and 8". The door to the closet or commode 10 will also preferably be rovided with a grating in the bottom simi ar to the grating 7 and 26.

As the air which is supplied to the interior of the car must necessarily have more -or less dust and clnders thereln, I mterpose between each inlet branch and the corresponding duct 11 or 11, a screen 28.

By the construction described and illus trated herein, it will be apparent that I have produced a comparatively simple and economical ventilating system for use with cars as the same are at present designed; that means are provided in connection with this system. for so supplying and distributing t e ventilating air and to secure this result without the c illing of the air and without inconveniencing the passengers; that I have provided means for efliciently and economically ventilating and removing the odors from the stateroom and general lavatories and closets; and that I have provided means whereby the air thus supplied for ventilation may be controlled as desired. If for any reason it should be desirable to cut out the ventilating system entirely, this result may be easily accomplished by merely swinging the valves or gates 14 in the appropriroj ecting branch of the. air-collecting li ead from the duct 11 or 11*.

Having thus described my invention, what I claim is l 1. The combination, with a car, of a pair of alr-supplymg ducts extending from the central portion of the car toward the opposlte ends of sald car respectively, said ducts being in alinement with each other and having lateral branches at their adjacent ends, means operative by the movement of the car in either direction for supplying air to said branches, an alr distributing duct beneathwith at their remote ends. and means including openings in the bottom of said, distributing duct for uniformly distributing the air throughout the length ofthe car.

2. The combmation, with a car, of an air supplymg duct extending longitudinally of said car, one end of said duct having a laterally extending branch an air distributing duct also extending longitudinally of said car and arranged alongside of said supply duct, said distributing duct'communicating with the end of said supply duct which is remote from said branch, means operative by movement of the car in either direction for supplying air to said branch, and means including openings in said distributing duct for uniformly distributing the airthroughout the length of the car.

3. In a ventilating apparatus for cars, in combination, a pair of air supplying ducts in alinement with each other and adapted to extend longitudinally of the car, an air distributing duct arranged alongside of said supply ducts, the ad acent ends of said supply ducts having laterally extending branches and their remote ends communi eating with the ends of said distributing duct, means operative by movement of the car in either direction for supplying air to said lateral branches, and means including openings arranged longitudinally of said distributing duct for uniformly distributing the air throughout the length of the ducts.

4. The combination, with a car, of a pair of air-supplying ducts extending from the central portion vof the roof of said car toward the opposite ends of said car respectively, an air distributing duct beneath the first-mentioned ducts and with which the discharge ends of said ducts communicate, means operative by the movement of the car in either direction for supplying air to the first-mentioned ducts, and means for controlling the distribution of air from the distributing duct into the car.

5. The combination, with a car, of a pair 'ing duct of air-collecting and supplying ducts each .extending from the upper central portion of the car toward an end thereof, means connected with the centrally located end of 7 each duct and operative by the movement of the car in either direction for supplying air to said duct, an air distributing duct with which the discharge ends of the first-mentioned ducts communicate, and means for controlling the distribution of air from the last-mentioned duct into the car.

6. The combination, with a car, of an aircollecting and supplying duct in the upper portion of the car, means operative by the movement of the car in either direction for supplying air to said duct, an air-distributbeneath the first-mentioned duct and communicating therewith, the last-mentioned duct being provided with longitudinally spaced air-distributing dampers, and one or more outlet flues within the car and having inlets adjacent to the floor thereof.

7. The combination, with a car, of an air conduit extending longitudinally of said car and comprising a distributing compartment extending substantially the length of the car, and two supply compartments one communicating with each end of the first compartment and terminating in an air receiving end at substantially the longitudinal center of said first compartment, and means communicatively connected to the receiving end of each supply compartment and arranged to collect air by the movement of the car in either direction.

In testimony whereof, I hereunto afiix my signature.
